` An objectf of theunVentiori*isl togenerally` improve windows; and to provide* a' deviceof that character which can be cleaned and otherwise serviced entirely from the inside of the house.

Another object of the invention is to provide a window through which ventilation may be had in various degrees throughout the full length of the window, even during a rain storm.

Another object of the invention is the provision of a window constructed and arranged in such manner that it is comparatively easy to replace broken glass, and to install the glass without the necessity of using putty or the like.

Another object of the invention is the provision of a window which may be adjusted for various degrees of ventilation and locked in any desired position.

Another object of the invention is the provision of a window constructed and arranged in such manner that even when fully opened, it would be impossible for an intruder to enter the house without breaking the glass.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawings forming part of the within disclosure, in which drawings:

Fig. 1 is a front elevation, with parts broken away, of a window embodying my invention.

Fig. 2 is a side elevation of the device illustrated in Fig. l, with parts broken away, showing the window in closed position.

Fig. 3 is a fragmentary detail of the device illustrated in' Fig. 2, showing the window in open position.

Fig. 4 is a section taken substantially on the line 4 4 of Fig. 2.

Fig. 5 is a section taken substantially on the line 55 of Fig. 3. f Referring now more particularly to the drawings, it will be understood that in the embodiment herein disclosed, my improved device consists of side jambs 1 and 8, head jamb 9, sill I0, and blind stops II, I2, I3, I4, l5, IS, I1, and IB, all of which may be secured together and mounted in the wall of a building in conventional manner.

Mounted for rotation in suitable apertures in the side jambs 1 and 8 are a plurality of spaced and aligned pivots I9, to the inside end of each of which is securely mounted a channel memberconnected to one another by spring members 25,

so that they may be worked in unison, yet be provided with a certain degree of resiliency to insure against breakage of the arms or the glass controlled thereby, in the event any of the elements should bind.

The upper and lower arms 23 on each side of the window are connected to rocker arms 26 and 21 (Fig. 2). The rocker arms 26 at the top are fixed to the ends of a rod 26A, and are adapted to rotate therewith. The rocker arms 21 at the bottom are pivoted as at 28, and are provided with racks 29, which are adapted to engage the pinions 3|), which in turn engage the worm gears 3I of a conventional assembly such as employed in opening and closing steel windows and the like.

The worm gear 3| is adapted to rotate by means of a crank 32, which is adapted to be inserted in a suitable socket 33 carried at the end of the worm gear 3I. The upper rocker .arms 2B and the lower rocker arms 21 are connected by means of chains 34, and move in unison.

It will be seen, therefore, that when the Worm gear 3| is rotated by means of the crank 32, the rocker arm 21 will move under the iniluence of the rack 29 and the pinion 30, causing the rocker arm 26 to move at the same time. When the rocker arms 21 rock in one direction, the rocker arms 26 will be similarly rocked by means of the chains 34; this will cause the upward movement of the arms 23, causing the window panes 2l to open. When the rocker arms 21 are rocked in the opposite direction, it will cause the arms 23 to be rocked downwardly under the influence of the springs 25, whereupon the panes will be moved into a closed position.

It will be seen, therefore, that with this arrangement the several panes comprising the window may be locked to any degree of open position, and may be held there in locked position.

In Figs. 4 and 5, I illustrate the manner in which a screen assembly 35 may be positioned on the inside of the window frame. In order to accommodate the screens 35I the side jambs 1 and 8 are slotted as at 36, so that the screens 35 may be inserted back of the blind stops Il and I2. I prefer to have the slot 36 comparatively deep in one of the side jambs 1 or 8, so that the frame of the screen 35 may be inserted asufcient distance, so that the opposite side of the screen will clear the blind stop adjacent thereto, and may be inserted behind the last--namedA blind stop. The screen may be removed by reversing the process.

It will, therefore, be seen that I have devised a novel window arrangement whereby various degrees of ventilation may be had during a rain.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a device of the character described, including a frame adapted to be mounted in a window opening, and having a plurality of panels of glasspivotally mounted therein,` the combination of an arm secured to each panel pivot, coil springs connecting theadjacent-arms, rocker arms at the top and bottom of eachframe, a chain connect- 4 ing the upper rocker arm to the lower rocker arm, and linkage connecting the upper rocker arm to one of said rst named panel pivot arms, and linkage connecting the lower rocker arm to 'another of said panel pivot arms.

2. The combination dened in claim 1, in which the said lower rocker arm has a rack thereon adapted to engage a pinion which is rotatable by means of a crank extending beyond the edge of said frame.
